Attention Battery Rebuilders! ToolkitRC M6D Chargers anyone?

Hi all previously asked this question in historic battery threads but it never gained much attention so decided to start my own thread.

So I purchased a few ToolkitRC M6D chargers but having problems with runaway charge, they are just not cutting out, ever. I went for these because they are tiny and capable of 15a discharge rate in recycle mode, attractive proposal!

Downloaded and installed the latest firmware, cables are 14awg turnigy silicone 250mm long, current settings are 4 amp charge and the lowest selectable "nixx peak" setting of 5mV but they just keep charging to the moon and blowing modules up until the relief valves pop, btw im only testing with low capacity junk modules and very well aware of the impact on modules charging to this point, I have done extensive testing over the last decade with my old chargers but I want to make a nice new test station with maybe 14 channels to get things done more efficiently

One thing that's not clear to me about these chargers is if the selectable peak (5mV to 15mV ) is per cell or for the complete module, i don't want to give up on them but meh its getting pretty annoying at this stage.

Has anyone else had a go at these little beauties yet?

 

Yes sorry millivolts is what i meant

 

Heyslayer thanks for the reply, i gave it a shot with a 5300mah module with "normal" ir and had to terminate the charge manually, watched it start to pull back somewhere around 8.82v

One thing i have noticed is at the start of a charge a note appears on the screen saying "charge to 9v" or similar, surely that does not mean its going to ignore delta and not stop until it reaches a target voltage lol? i have been all through the menu and there is no way to switch that feature off.

I know some of the cheaper chargers like the imax had issues with delta peak charging on the nimh toyota modules but these toolbox chargers are a slightly better than the imax, better support and somewhat of a following! not premium but not bottom of the barrel either, the hobby guys rate them highly but they are mostly using them for lipos no doubt

 

Its not a problem just that's where it peaked, I cant remember the exact voltage maybe it was actually 7.92 not .82 I'm not sure.. but either way I watched it peak and start to go backwards so I manually terminated charge it had input about 7700mah and started to swell..

I plan on charging at 1C and discharging at 2C which is what I have always done and had good success with, I have a purpose built cooling dock that I sit the pack on in the summer time

I'm sure others here must have tried these chargers by now, they are about 4/ 5 years old and pretty common, just a matter of them noticing the thread and if they feel like chiming in I guess
